Not recognising SSD

Takaharu · Apr 27, 2010, 04:03 PM

I bit the bullet last week and ordered an Intel X25-V 40GB and installed Windows 7 on Saturday.
All seemed to be running like grease lightning but I discovered that Prefetch (I think it was called) and defrag on the C drive was still available.

Things I've checked:

BIOS is up to date (1403 on ASUS Maximus Formula)
Firmware is up to date
Changed SATA mode from IDE to AHCI (sp?)
Re-installed Windows after changing SATA mode and updating the firmware
Ran the Intel SSD Toolkit - all tests passed
Hard drive rating in Windows is 7.7
Manually changed registry settings to match SSD settings (like you would for XP)

Should I be concerned that Windows hasn't automatically disabled prefetch and defrag?

I don't think you should be too concerned, as long as the speed you're getting seems to be what Intel has claimed for that drive and you have made sure that prefetch and defrag are definately disabled. I don't think windows would let you do a defrag on the harddrive anyway.

but you're better off checking if anyone else has had the problem just to be sure

TRIM should be enabled if you did a fresh Windows 7 install. To find out if it is follow below.

Go to a Command prompt and type> fsutil behavior query disabledeletenotify

DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

I got:
DisableDeleteNotify = 0

So in that sense it sounds promising.

yep, you should be good to go. Also might try CrystalDiskInfo tool just to make sure

Windows never disables Superfetch or defrag. It just never gets run on a drive it recognizes as an SSD. DisableDeleteNotify will always be set to 0 as well. No matter what drive you have installed. Windows always sends the ATA TRIM command. That doesn't mean that the SSD is receiving it. You don't even need the toolkit to get TRIM to work. It wasn't until the most recent Intel Rapid Storage drivers did TRIM get passed w/ the Intel drivers installed.

CrystalDiskInfo gave SSD info so all looks good.

The first time I installed Windows it started off with a rating of 7.7 then after a couple of reboots went down to 5.9. This time it hasn't, which is a relief. Might've been the firmware, SATA mode or a mix of both.
